RoadRunner FBL information

RoadRunner has decided to delay the launch of their new FBL until after the holidays. Sounds like a good idea to me, the launch is never quite as smooth as the ISP wants it to be. People are checking out and trying to troubleshoot the problems while also dealing with all the extra stress and […]

Co-reg

Well over half of the clients who come to me with delivery problems admit at some point that one of the ways they collect subscribers is through co-registration. They typically have widespread delivery problems at the major ISPs as well as SBL listings. John Levine posted over the weekend about his thoughts on co-reg. So […]

Blocking mail to spamcop.net

Josh reports mail from MobileMe to spamcop.net addresses is being filtered somewhere and isn’t being delivered or actively bounced. He asserts that Apple is blocking all mail to Spamcop addresses because they were having problems getting blacklisted on SpamCop and implemented this as a way of reducing their number of SpamCop spamtrap hits. That makes […]

Aggregate stats for benchmarking

The great folks over at Mailchimp publish aggregate stats from their customers. This is a useful set of data for senders who want to see how other mailers or ESPs are doing.

But that’s what spammers do!

A few weeks ago I was asked my opinion about a delivery situation. It seems that a sender wanted to mail to a purchased email list. They asked what I thought about getting fresh IP addresses and domains to use to send mail to the purchased list. “We know we’re going to get complaints, probably […]

Confirmed unsubscribe

Whatever one might think about confirming opt-ins I think we can all agree that requiring someone to jump through hoops and confirm an unsubscription request will just annoy that person. Today I attempt to opt-out from a discussion list. It’s one I *thought* I had opted out of previously, but I could find no record […]

  • AOL compromise

    Lots of reports today of a security problem at AOL where accounts are sending spam, or are being spoofed in spam runs or something. Details are hazy, but there seems to be quite a bit of noise surrounding this incident. AOL hasn't provided any information as of yet as to what is going on.4 Comments

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail. This has nothing to do with spam, filtering or malicious email. This is simply their servers aren't functioning as well as they should be and so AOL can't accept all the mail thrown at them. These types of blocks resolve themselves. 1 Comment
